What insertion length should you choose for a flameproof temperature sensor going into a mid-sized reactor or storage tank?
For mid-sized vessels, reactors, and pipeline headers, a 1200mm flameproof temperature sensor is often the correct middle-ground choice between a too-short 300mm probe and an unnecessarily long multi-meter sensor, and this PT100 model is available factory-direct at a transparent fixed price with zero middleman markup and ready stock for fast nationwide dispatch.
Built as a simplex, 3-wire PT100 element on a 6mm SS316 sheath, this sensor is rated for a -50°C to 400°C process range with Class A accuracy, ensuring the resistance-temperature relationship remains repeatable and stable across demanding thermal cycles — critical for both process indication and closed-loop control applications in hazardous-area installations. The adjustable 1/2″ BSP compression fitting lets engineers fine-tune the mounting depth during installation, which matters at this length because mid-sized vessel geometry can vary between projects and the ideal insertion depth isn’t always known until commissioning. Compacted MgO insulation runs the full length of the probe, accelerating thermal response time while protecting the internal wiring element from mechanical vibration over the extended 1200mm span — a real durability consideration compared to shorter sensors. The die-cast aluminum head carries an IP67 rating with a threaded cap and safety chain to protect the termination compartment from dust and washdown moisture, and the nickel-plated ceramic terminal block provides a stable, corrosion-resistant wiring connection. This sensor is manufactured by Aavad Instrument Pvt. Ltd. under ISO 9001:2015 certified manufacturing processes and is CE marked, confirming it meets applicable EU safety, health, and environmental protection requirements.

FAQs
1. How do I know if 1200mm is the right length for my vessel?
To determine the appropriate 1200mm insertion length, measure from the outer vessel wall or process flange to the estimated center of the process flow or the zone where the most representative temperature needs to be measured. Consider the vessel diameter, process flow, and thermowell or sensor mounting location. If a shorter or longer reach is required, compare available variants such as 300mm, 600mm, 900mm, and 2400mm+ in the same product range.
2. Is this sensor suitable for both indication and control loop use?
Yes. With Class A accuracy and a -50°C to +400°C temperature range, this RTD sensor is suitable for both local or system temperature indication and closed-loop process control applications. It can be integrated with compatible temperature transmitters, PLCs, DCS systems, or process controllers depending on the required control architecture.
3. What’s the lead time if I need a custom length between standard sizes?
Standard lengths are available from ready stock where applicable and can be dispatched promptly. For a custom insertion length between standard sizes, contact our team with your exact length and application requirements. We will confirm technical feasibility, available configuration, and expected lead time before you place the order.
